To all whomvlt may concern Be it known that we, Ross L. REYNOLDS and ALFRED D. MoGRAw, both of Fall River,

in the county of Bristol and Commonwealth of Massachusetts, have invented an Improvement in Saddles for the Top Rolls of Spinning-Frames, ,of which the following de scription, in Connection with the accompany ing drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to saddles which are used in connection with stirrups to put weight on the top rolls of ring spinning frames. The proper operation of the said rolls requires an additional weight to be put upon them beyond the weightof the rolls themselves. This is customarily done by a saddle resting on the rolls and carrying a stirrup which is drawn down by a weight. The distance of the two front rolls from each other varies according to the kind of cotton in use; and it is necessary that the saddle should be so constructed as to keep the weight either on all three rolls, or on the front and back rolls alone as the work re quires.

In the annexed drawings Figure 1 is a top view of the top rolls and our improved saddle. Fig. 2 is a vertical sectional view of the same showing the saddle so adjusted as to put weight on the middle roll. Fig. 3 a vertical sectional view showing the saddle so adjusted as to put no weight on the middle roll. Fig. 4 is a cross section on line w, '0, Fig. 1. Fig. 5 is a cross section on line to, 2, Fig. 1. Fig. 6 is a vertical sectional view of an alternative construction of the slide. Fig. 7 is a top view of said last named construction. Figs. 8 and 9 are views of the slide and stirrup on line a? y showing how the stirrup is retained by the slide. Fig. 10 is a sectional View of another construction; and Fig. 11 is a top view of said last named construction. a

The saddle is composed of two principal pieces, viz: the front saddle E having the bearing 6 for the front roll I, i, and the elongated shank Gr having the slot 6; and

I the back saddle H having the curved bean loetedas shown at e.

is suspended the stirrup B. I The slide A has the longitudinal slot at through which passes the set screw 0 which is threaded into "In the front portion of the-slide is atransverse slot at in which the front saddle and serves to retain the ,ad-

'justnient of the slide A. The under side of the shank G is rounded and is adapted to engage and slide in corresponding recesses formed by projecting shoulders if, 71, on the top of the back saddle H. Thesetscrew F passes through the slot 6 in the shank G and is threaded into the back saddle. serves to retain the adjustment between the front saddle and the back saddle. On the top of the front saddle is the oil well P, P

from which the oil holes p, p, p, p, shown only on Figs. 6-11 lead to the front roll hearing. The oil well may if desired be filled with felt or some other absorbent material.

Figs. 6 and 7 show an alternative construction of the slide. The slide A is rounded, is slotted longitudinally and engages and slides in the rounded recess a in the top of 'the front-saddle, back of the oil well. It is provided with a circumferential groove A Within said groove the slide A is elliptical in form, wider on its horizontal than on its VGItlCEll diameter, the groove being of uneven depth. The hole in the stirrup B is f ing sufficiently wide to allow the grooved portion of the slide A to enter said hole when said slide is turned at right anglesto its normal position.

the minor diameter of the elliptical portion of the slide A, and is lessthan the major diameter of said elliptical portion. After the stirrup has been mounted on theslide, the slide is then turned into its usual position, Fig. 8, and the stirrup. B and the The.

at itsrear end A and is retained by the adjust-ing screw C Toward the front of the stirrup-slide A are a number of transverse slots on the underside. The stirrup itself is, in this construction, suspended dicut away at its lower edge, leaving an open- I so a In other words the openinginto said hole is slightly wider than rectly on the front saddle. The stirrup slide A is then engaged over the stirrup, and the engagement is retained by the set screw C Having thus described our said invention, We claim: a

1. A top-roll saddle consisting of a frontsaddle having a straight elongated slotted shank adapted to engage the back-saddle on the under side of the front-saddle at two points, a back-saddle longitudinally adjustable With reference to the front-saddle and Wider portion of the stirrup-slide, said recessbeing Wider than the opening into it.

3. In a top-roll saddle, a front-saddle adapted to engage the back-saddle, a backsad'dle, a stirrup-slide mounted on the frontsaddle, a stirrup supported on said slide, and means to lock said stirrup and said slide together against vertical motion of the stirrup With respect to the slide.

4. In a top-roll saddle, a front-saddle adapted to engage the back-saddle at two points, a back-saddle, a stirrup-slide engaging the front-saddle and adapted to slide thereon, a stirrup engaging said slide, and

means to fasten the stirrup and the slide together against vertical movement of the stirrup With respect to the slide.
